Bathe in freshwater
In 2002, a study on a salmon farm in Tasmania, Australia (Clark et al., 2003) found an 86% reduction in the number of live amoebae found on the gills of salmon, Salmo salar, after freshwater bathing. The presence of amoebae increases the risk of amoebic gill disease. The lower levels of amoebae persisted for 3 days before gradually increasing to pre-bathing levels on day 10. Salmon were given freshwater baths for two hours then monitored for 10 days. Samples were removed from fish before bathing and at 1, 3, 5 and 10 day intervals after bathing to determine the number of amoebae present on the gills.
